This is such an exquisite weight. Swirls of iridescent multi-colored particles that produce an amazing effect. It is an abstract work of art. R. W. Stephan is very much in demand. This is a rare early weight by R. W. Stephans, who established his Glassworks, Inc. Studio. He no longer makes this beautiful style of an iridescent rainbow swirl, and the infrequent examples being offered are priced at many hundreds of dollars when available. The swirling glass particles reveal iridescent rainbows changing with every turn, every change of light. The swirls are speckled seemingly with flakes of jewels and are fascinating.
